Abstract (en)
A water level sensor, a steam generator having the same, a heating cooker having the steam generator and a control method of the heating cooker implement embodiments of the present invention. The water level sensor stably senses the change of a water level regardless of the production of scales. The heating cooker includes a cooking chamber in which food is put; a steam container generating steam to supply the steam to the cooking chamber; a water supply supplying water into the steam container; a steam heater heating water in the steam container; a water level sensor installed in the steam container to sense a change of a water level in the steam container; and a controller controlling the water supply in accordance with the sensor output value of the water level sensor, wherein the water level sensor has one electrode rod to detect a change in electrostatic capacity in accordance with a change of a water level.
